I think you forget, or choose to ignore, how appalling the 10 people in front of him have been. If you expect a keeper to make up for the failings of the other 10 players at all times, you're going to be disappointed an awful lot.

No, I remember when he had a decent 10 in front of him, an attacking force that could have made the playoffs had we been able to keep a few more goals out of our own net. I said then the weak spot was the goalkeeper position. It's become less obvious as the quality was sold off and replaced with dross. But then that confirms the problem, if he was good enough he'd have stood out as the star man in a side that never looked worthy of staying in the Championship.
